Belt Sander Vs Disc Sander | Which sanding device is best for your workshop ?

Whether you are in a woodworking trade, a pro-grade woodworker or an occasional DIY enthusiast, a sander is the most required tool to have it handy. The tasks performed by a sanding machine are shaping, removing, and smoothing wood surfaces. However, things get challenging when there are so many models available in the market and you have to pick one out of all. But which one should be picked is the question.

Though there are several types of sanders, I will break down the features, utilities and budget, and more of belt sander and disc sander, so that it helps you make the right decision. 

Let’s begin…

What is Belt Sander? What are its applications?

Belt Sander is also called strip sander and is powered by an electric motor, which initiates a rhythmic movement of the drums pair into this sander machine. These drums include some sandpapers loop-mounted onto them.

Again, belt sanders can be of two types: stationary and non-stationary. In the case of a stationary belt sander, you have to move the wood slice onto the sander belt. Conversely, you can put the non-stationary belt sander into motion onto the workpiece. 

Applications of a Belt Sander 

  • Trimming the rims of the wooden piece
  • Rounding and shaping the wooden log
  • Sanding rough wood surfaces or plate
  • Wood log leveling for making new  platforms like table, desk, or other furniture 

What is Disc Sander? What are its applications?

Disc Sander is a high-powered machine operated by an electric power/ compressed air to initiate sanding in rotational motion. This machine is used to sand wood where the sander moves a circular disc/platter along the central axis.

A coarse disc containing abrasive particles is adhered to the circular platter. This abrasive disc removes wooden debris or paint rust (if any) from the wooden slice. 

Applications of a Disc Sander 

  • Sanding and removing debris or rust from the surface of the wooden slice
  • Grinding away the paint from the wood
  • Removing waste from the wooden as well as plastic surface
  • Allows sanding of plastic materials, too

Let’s have a look at the differences and similarities between belt sander and disc sander concerning their respective features. 

FeaturesBelt SanderDisc Sander 
SpecialityThey can be both stationary and non-stationary wood sanders. They are the stationary type of wood sander. That means the wood piece has to be moved onto the sander.
Mechanism of OperationFunctions by moving the abrasive sandpaper, containing up and down drum pairs, on the rougher surface of the wooden block. The wheel or platter with the attached circular sandpaper is rotated along its center axis by an electric powered motor or compressed air.
Fit forSanding any plain/flat surfaceSanding the edges 
Price RangeEven the best belt sander won’t cost you more than $200. The minimal pricing would be around $50. However, considering some particular models, prices may increase, in case you are looking for added features and upgraded technology.The minimum cost can be as low as $40 or even lesser and can be as high as several 100 bucks. But, $50 to $300 is a pretty fair range to get a laundry list of disc sanders available on the market to choose from, with respect to specific features and performance demands.
